thanks!

[haraldh]

why did you close this??!!

[jarkkojs]

I thought that allocation is done with mmap() et al. I don't see what this task would cover that other tasks do not.

[jarkkojs]

I.e. tasks: #1496, #1506 and #1531.

We need an internal shim allocator in KVM, SNP and SGX.

[haraldh]

This is needed to have access to the alloc crate and for Box and drop and all the collections.

When we want to keep poll fd book keeping and other syscall filtering we most likely want to use some collections for it.

[jarkkojs]

OK the issues were quite unclear what the heck they are so I did a big misinterpretation. Sorry about that.

[jarkkojs]

@haraldh Should I implement this (at some point)? It's pretty easy by reusing mmap() code.

@haraldh do you know what is the situation here?

[haraldh]

I just implemented the global allocator in shim-kvm which enables the use of the alloc crate (part of rust standard libs).

For shim-sgx, we should do the same.
